ID is the first fully customized progressive
lens, designed using IDSD technology and
shaped to the specific rotation of your
eyes. The more you rely on your glasses, the
more you’ll appreciate the ID lens.

HOYA’s Free-Form design approach is based on
the understanding that no two eyes are the
same. Our patented Integrated Double Surface
Design (IDSD) technology maps the specific
rotation of each eye, creating the blueprint
for lens construction. HOYA Free-Form
Fabrication then uses diamond point tools to
shape both sides of the lens to the exact
specifications of your eye rotation.

Progressive lens designs have always
restricted the vertical and horizontal
design components to the same side of the
lens. HOYA is the first to customize the
lens on both sides, creating a truly
personalized vision correction.

Our patented Integrated Double Surface
Design (IDSD) process shapes the vertical
component (which affects magnification and
distance) into the front of the lens, and
the horizontal component (which affects the
power changes from side to side) into the
back. The two surfaces are then integrated
using Balanced View Control, our computer
vision evaluation that analyzes and corrects
any Skew Deformation, ensuring the clearest
vision in all directions.
